The problem Wiener systems identification is addressed in presence of hysteresis nonlinearities, presently described by the Bouc-Wen model. The latter is nonlinear differential equation involving unknown parameters, some of which coming in nonlinearly. Except for stability, the linear subsystem is arbitrary and, in particular, it is not given a particular structure. By using sine excitations, t...

In the marine environment, naval vessels are often influenced by underwater compression waves. Transport and dangerous goods require advanced protection beyond linear, static considerations. Therefore with regard to shock influence, dynamic characteristics of helical wire-cable-isolators investigated. The impact is given basepoint acceleration measurement data exciting a mechanical model observ...

To compensate for missing functions of lower extremity amputees, this paper proposes a model of an intelligent bionic leg semi-actively controlled by a magnetorheological damper (MRD). A mechanical structure of the leg is designed, and with the help of Bouc-Wen model, a MRD forward dynamics model is constructed for simulation. On the basis of data obtained from simulations, the MRD inverse dyna...

Most studies tackling hysteresis identification in the technical literature follow white-box approaches, i.e. they rely on the assumption that measured data obey a specific hysteretic model. Such an assumption may be a hard requirement to handle in real applications, since hysteresis is a highly individualistic nonlinear behaviour. The present paper adopts a black-box approach based on nonlinea...

The hysteretic behaviour is an essential feature of many physical systems. Such a feature is conveniently accounted for in hysteretic systems modelling through the well known nonlinear Bouc-Wen equations. But these involve several unknown parameters and internal signals that are not all accessible to measurements. These difficulties make the identification of hysteretic systems a challenging pr...
